摘要： A method of producing a medium-tight connection between interior and exterior concentrically-arranged glass tubes includes the steps of providing a longitudinally extending electrical conductor strip between the interior and exterior tubes, forming a bulge extending radially outwardly from the interior tube by heating the tube, inserting the interior tube into the exterior tube, and forming a constriction in the exterior tube which extends radially inwardly and connects with the radially outwardly extending bulge to form a closure area, whereby the conductor strip passes through the closure area. An electrochemical sensor for measuring pH values or redox potentials formed according to this method includes an elongated housing which contains an interior chamber defined by the interior tube, a glass membrane cap, and a closure member, and an annular exterior chamber defined by the interior and exterior tubes. The interior chamber contains a buffer solution which covers at least a portion of a working electrode, the working electrode being further connected with an electrical line which passes through the closure member for connection with a connection point located outside of the interior chamber. The exterior chamber contains a reference solution which covers at least a portion of a reference electrode, the reference electrode being connected with an electrical line which extends from the exterior chamber through the medium-tight connection area formed in accordance with the invention to a connection point located outside of the exterior chamber.
